请帮我用英语介绍一下盐
包括负作用,正能量作用以及介绍.下面这些可供参考.请不要直接翻译,只是供参考.
盐是指一类金属离子或铵根离子（NH4+）与酸根离子或非金属离子结合的化合物.如氯化钠,硝酸钙,硫酸亚铁和乙酸铵等,如硫酸钙,氯化铜,醋酸钠,一般来说盐是复分解反应的生成物(盐与盐反应生成新盐与新盐,盐与碱反应生成新盐与新碱,盐与酸反应生成新盐与新酸）,如硫酸与氢氧化钠生成硫酸钠和水,氯化钠与硝酸银反应生成氯化银与硝酸等.也有其他的反应可生成盐,例如置换反应.可溶性盐的溶液有导电性,是因为溶液中有可自由游动的离子,故此可作为电解质.

Answer 1

Salt is a kind of metal ions or ammonium ion (NH4+) compounds in combination with ion or non metal ions.Such as sodium chloride,calcium nitrate,ferrous sulfate and ammonium acetate,such as calcium sulfate,cupric chloride,sodium acetate,generally salt is the product of double decomposition reaction (salt and salt reaction to generate new salt and salt,salt and alkali reaction of new salt and alkali,salt reacts with an acid to form a salt and acid),such as sulfuric acid and sodium hydroxide to generate sodium sulfate and water,sodium chloride and silver nitrate of silver chloride and nitric acid reaction.There are other reaction producing salt,such as the replacement reaction.The soluble salt solution conductivity,is because the solution with ion free swimming,therefore can be used as electrolyte.累死我了,要追加分啊
